BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a radiator core and, more particularly, to a tube module of a radiator core of a car.

2. Description of the Related Art

A conventional radiator core comprises a head tube, a bracket, and a plurality of tubes. The tubes are mounted on the head tube. The tubes provide a heat dissipation effect to the radiator core. When the two opposite sides of the tubes are subjected to a force or stress, the tubes are easily broken at the two opposite sides so that water leak is easily produced in the radiator core. Thus, the producer has to mount reinforcing plates on the tubes to enhance the strength of the radiator core, thereby preventing occurrence of breaking or leaking. However, the producer has to provide and assemble the reinforcing plates on the tubes, thereby increasing the cost of fabrication, the working time and the procedures of assembly.

In accordance with the present invention, there is provided a radiator core comprising a head tube and a tube module mounted on the head tube. The head tube is provided with a plurality of tube slots. The tube slots of the head tube include a plurality of first sides and a plurality of second sides. The tube module includes a plurality of first tubes and a plurality of second tubes. The first tubes and the second tubes of the tube module are mounted in the tube slots of the head tube. Each of the first tubes is a hollow tube formed integrally by bending a sheet plate. Each of the first tubes has a first side provided with a first connecting portion and a second side provided with a first rim. The first connecting portion of each of the first tubes has a thickness more than that of each of the first tubes. The first connecting portion of each of the first tubes rests on one of the first sides of the tube slots of the head tube. The first rim of each of the first tubes is a seamless chamfered angle. Each of the second tubes is a hollow tube formed integrally by bending a sheet plate. Each of the second tubes has a first side provided with a second connecting portion and a second side provided with a second rim. The second connecting portion of each of the second tubes has a thickness more than that of each of the second tubes.
